9.8-GW tabletop attosecond light source
Lihui Meng, Lu Xu, Xusheng Zhu +4
The generation of attosecond pulses has enabled real-time observation and manipulation of coherent electron dynamics, yet their low peak power has hindered the development of advan…
Quantum Trajectory Separation and Attosecond Mapping in Liquid High-Harmonic Generation
Wanchen Tao, Ruisi Zhang, Qihe Guo +5
High-harmonic generation (HHG) from liquids offers a potential pathway to attosecond spectroscopy in chemically complex and disordered environments, yet fundamental questions remai…
Instantaneous optical selection rule for independent control of valley currents
Wanzhu He, Xiaosong Zhu, Liang Li +4
We reveal an instantaneous optical valley selection rule that illuminates the coupling between the instantaneous optical chirality of the driving laser field and the chirality of v…
Unveiling unique ultrafast nonlinearities in liquid-phase high-order harmonic generation
Wanchen Tao, Zhuang-Wei Ding, Lixin He +5
High-order harmonic generation (HHG) provides a powerful optical tool for probing ultrafast dynamics on the attosecond timescale. While its mechanisms in gases and solids are well-…
"Molecular waveplate" for the control of ultrashort pulses carrying orbital angular momentum
Chengqing Xu, Lixin He, Wanchen Tao +8
Ultrashort laser pulses carrying orbital angular momentum (OAM) have become essential tools in Atomic, Molecular, and Optical (AMO) studies, particularly for investigating strong-f…
Attosecond All-Optical Retrieval of Valley Polarization via Circular Dichroism in Transient Absorption
Wenqing Li, Xiaosong Zhu, Pengfei Lan +5
We propose a scheme for retrieving the ultrafast valley polarization (VP) dynamics in two-dimensional hexagonal materials via attosecond circular dichroism (CD) transient absorptio…
Helicity-selected near-circularly polarized attosecond pulses generated from mixed He-Ne gases
Chunyang Zhai, Xiaosong Zhu, Yingbin Li +4
We present and theoretically demonstrate a method for generating helicity-selected near-circularly polarized attosecond pulses in mixed He-Ne gases using bichromatic counter-rotati…
High-purity valley-polarized currents induced by bichromatic optical fields in two-dimensional materials
Wenqing Li, Xiaosong Zhu, Liang Li +4
Producing currents predominantly from a single valley, namely valley-polarized currents, at optical-cycle timescales is an important aspect of the petahertz valleytronics, yet it r…
